37. Antitumor efficacy of piperine in the treatment of human
HER2-overexpressing breast cancer cells. (2013)
▪ Piperine is a bioactive component of black pepper, Piper nigrum Linn, commonly used for daily
consumption and in traditional medicine.
▪ Here, the molecular mechanisms by which piperine exerts antitumor effects in HER2-overexpressing
breast cancer cells was investigated.
▪ The results showed that piperine strongly inhibited proliferation and induced apoptosis through
caspase-3 activation and PARP cleavage.
▪ Furthermore, piperine inhibited HER2 gene expression at the transcriptional level.
▪ Blockade of ERK1/2 signaling by piperine significantly reduced SREBP-1 and FAS expression.
▪ Piperine strongly suppressed EGF-induced MMP-9 expression through inhibition of AP-1 and NF-κB
activation by interfering with ERK1/2, p38 MAPK, and Akt signaling pathways resulting in a
reduction in migration.
▪ Finally, piperine pretreatment enhanced sensitization to paclitaxel killing in HER2-overexpressing
breast cancer cells. Our findings suggest that piperine may be a potential agent for the prevention
and treatment of human breast cancer with HER2 overexpression.

40. PHARMACOKINETICS OF PIPERINE IN RAT
▪ Oral : 97% of piperine was absorbed after oral administration of piperine at a dose
of 170mg/kg to the male albino rats.
▪ It is metabolized rapidly by liver and other tissue and maximum plasma
concentration was attained at about 6 hr
▪ 3% of the administered dose was excreted up to 4 days as piperine in the feces and
it is not detectable in urine
▪ Half life (t½) was found to be 18.24 hr.
▪ About 36% of the orally administered piperine was excreted as conjugated phenols
in urine and 62% as methylenedioxyphenyl metabolites

47. Herbal formulation "turmeric extract, black pepper, and ginger"
versus Naproxen for chronic knee osteoarthritis:
A randomized, double-blind, controlled clinical trial (2020)
▪ Osteoarthritis is the most common articular disease that can lead to chronic pain and
severe disability. Curcumin-an effective ingredient in turmeric with anti inflammatory
property-plays an important role in protecting the joints against destructive factors.
Gingerols and piperine, are the effective ingredients of ginger and black pepper, which
may potentially enhance and sustain the effect of curcumin in this direction. To
determine the effect of cosupplementation with turmeric extract, black pepper, and
ginger on prostaglandin E2 (PGE2 ) in patients with chronic knee osteoarthritis,
compared with Naproxen. Sixty patients with two different levels of knee osteoarthritis
(Grade 2 and 3) were studied. Individuals were randomly assigned to receive daily
turmeric extract, ginger, and black pepper together or Naproxen capsule for 4 weeks.
PGE2 was evaluated by ELISA method. 24-hr recall was also assessed. All of participants
completed the study. PGE2 decreased significantly in both groups (p < .001), but there
was no significant differences between groups. The results of this study indicated that
intake of the selected herbs twice a day for 4 weeks may improve the PGE2 levels in
patients with chronic knee osteoarthritis similar to Naproxen drug.
▪ Keywords: Naproxen; black pepper; ginger; knee osteoarthritis; prostaglandin E2;
turmeric extract.

49. Acute toxicity of piperine in adult mice (1983)
▪ The LD50 values of piperine in adult male mice were:
▪ Intravenous 15.1 mg/kg
▪ Intraperitoneal 43 mg/kg
▪ Subcutaneous 200 mg/kg
▪ Intragastric: 300 mg/kg
▪ Intramuscular 400 mg/kg
▪ Most animals given a lethal dose died of respiratory paralysis
within 3-17 min
▪ Histopathologic changes included severe hemorrhagic necrosis
and edema in gastrointestinal tract, urinary bladder and adrenal
glands.

50. Piperine Drug Interactions
▪ Piperine ( 20 mg/day) may increase plasma concentrations of
▪ carbamazepine
▪ midazolam
▪ Diclofenac
▪ Fexofenadine
▪ It is not clear whether dietary use of black pepper would result
in clinically significant drug interactions
